The Mercurosaurus Rex makes his way across the prehistoric carpet. 

This is Mercury the cat. He was found at four days old, weighing only five ounces and missing his two front limbs, the possible result of a weed whacker mishap. Things weren't looking so great for him at that moment, but he was taken in to a local vet where he had his wounds cleaned, and then he was handed off to a couple who were willing to take care of him.

Now, some cats in this situation would be all like, "Mew... I only have two legs. I can't cat with only two legs." But not Mercury. No, Mercury was like, "If I can't cat with only two legs, then I'm gonna goddamn dinosaur around this place. Raaawwrrr!!!"
